It may also be beneficial to contact your local support center. They may be able to isolate the issue a bit quicker than we can over the forum. You can find local support contact details by visiting http://global.bose.com and selecting your country from the drop-down menu.
Let us know if that helps at all.
Before we get any deeper into the technical aspects of this problem, let's clarify a few specific points about the symptom. In the SoundTouch app you can select at the top to browse by Tracks, Artists, Albums, etc. and normal track-listing behavior is as follows:
Can you clarify whether selecting "Albums" at the top and selecting just one album shows the wrong order? Or does this happen only when browsing in the other two categories?
Also, when you mention iTunes in your last post, do you mean that you are transferring the files to your computer and adding a separate library from there? Or are you simply making modifications to the ID3 tags for files still on the NAS drive?
Let us know.
If adjusting the ID3 tags for the files manually is correcting the issue, then the tag information was likely our trouble all along. That tag information is what the LaCie drive uses to build its DLNA server index, which is in turn what the SoundTouch app reads to browse the library.
Fixing this info may be the only way to solve the problem, but iTunes may not be the best tool for the job. There are a number of free third-party software solutions (MediaMonkey, ID3tag, etc. ) out there which can assist in the process of bulk-editing the info for your music files.
